Size: U1-PRO-800
Nice quality plenty of cranking power put it in my Ferris Zero Turn and fit perfectly!! Surprised having a switch and digital display on the top of the battery giving you display of the capacity and voltage very nice feature! Shipping was very well secure in 2 box's and had plenty of packing to keep battery safe during transport! Update: Enjoyed it so much I ordered a 2nd one for my EZ-GO Commercial 4x4 golf cart with a Honda V-Twin and it cranks over better and faster than any led acid battery I have ever had on it! ... show more
